Identity & origin
BOTANICAL IDENTITY
The right name is the first step.
Kew describes this taxon as an annual or perennial. This notice concerns Plantago major, family Plantaginaceae. The pharmacopoeial material is: leaves.
Results are presented to explain the research; no self-medication recommendation.
Also known as: Plantain, Plantago major
Plantago major, Plantago lanceolata and psylliums are distinct plants. The leaf covered here does not inherit indications for psyllium seed husks.A photograph alone does not guarantee identification for consumption.
An illustration is not enough to identify a plant for consumption. Do not forage for a species based solely on this profile.
Uses & evidence
UNDERSTANDING THE USES
Properties & uses.
Bronchitis: syrup studied in adults
A broadleaf-plantain syrup showed a clinical cough signal. The studied formula does not validate every preparation of harvested leaves.
A human study may be positive, negative or inconclusive. Read the findings, preparation and limitations.
Read the sourceThe traditional uses described are not clinical proof of effectiveness. Evidence for one preparation cannot automatically be applied to another.
Precautions before use
BEFORE ANY USE
Precautions & contraindications.
This guidance does not cover every individual situation. Missing information is not a guarantee of safety.
Contraindications & precautions
- Insufficient dataThis targeted audit does not provide a comprehensive contraindication review; this does not mean contraindications are absent.
Medicine interactions
- Insufficient dataThis dossier cannot establish compatibility with medication. A limited study does not replace an interaction review of the exact product.
Other retained warnings · review incomplete
These existing warnings remain relevant to consult. Their exhaustive reassessment is outside this targeted review.
Restrictions and precautions
- The references in this notice do not establish a complete contraindication list. This limitation does not mean absence of risk.
Medicine interactions
- Medicine compatibility is not assessed in this notice; a pharmacist should check it before any use.
Pregnancy, breastfeeding and children
The retained data do not support recommending medicinal use during pregnancy or breastfeeding.
No paediatric use is proposed; pharmacopoeial listing does not establish a child-appropriate dose.
“Reported” does not prove causality; “possible” may reflect indirect evidence. “None reported” means none in the cited source, not that all combinations have been studied. Do not stop a prescribed treatment based on this profile.
Adverse effects
- Trial size and duration cannot rule out rare or delayed effects. Tolerability of the tested product does not apply to every preparation.
Pregnancy & breastfeeding
The retained data do not support recommending medicinal use during pregnancy or breastfeeding.
Children & adolescents
No paediatric use is proposed; pharmacopoeial listing does not establish a child-appropriate dose.
If symptoms persist, worsen or are unusual, consult a healthcare professional. In an emergency, contact the emergency services.
Available evidence
EXPLORE THE EVIDENCE
The available evidence.
A broadleaf-plantain syrup showed a clinical cough signal. The studied formula does not validate every preparation of harvested leaves.
Bronchitis: syrup studied in adults
The bronchitis-severity score decreased more than with placebo.
A human study may be positive, negative or inconclusive. Read the findings, preparation and limitations.
Read the referenceLimitations to keep in mind.
Breathlessness, high fever or persistent cough warrant medical advice. No home dose is inferred from the trial.
Studies, findings & limitations
THE RESEARCH
What the research shows.
A laboratory or animal result alone does not demonstrate a benefit in humans. Each result must be read alongside the preparation studied and its limitations.
Bronchitis: syrup studied in adults
A human study may be positive, negative or inconclusive. Read the findings, preparation and limitations.
- Type of research
- Double-blind randomized trial, 80 adults, ten days.
- Preparation concerned
- Plantago major syrup.
- Observed results
- Cough frequency, sputum and quality of life also favoured the tested syrup.
- Limitations to consider
- A single short trial does not resolve paediatric safety, pregnancy or chronic respiratory disease.
What can we take from this?
A single short trial does not resolve paediatric safety, pregnancy or chronic respiratory disease.
